    摘要: A ground cover sheet material for use in agriculture is woven from warp and weft tapes of a plastics material and at least some of the warp or weft tapes have a greater width and/or thickness than the weft or warp tapes, or the material includes a higher density of warp or weft tapes relative to the weft or warp tapes per unit area, or includes slits through the tapes, or the tapes are folded lengthwise, all optionally in one or more high water flow through lengthwise extending parts of the material. In one embodiment the material is woven from warp or weft tapes some having a rectangular or square cross-section and some having a circular or oval cross-section. In some embodiments the material is also a reflective material.

    摘要: A slit yarn wherein both side parts of the slit yarn are folded one or more times, and the folded width is substantially uniform along the direction of length of the yarn. In this slit yarn, when the width is measured at 20 or more points at intervals of 0.5 m, and the fluctuation coefficient X shown in the following Equation (1) is calculated on the basis of the average value W(avg) and the standard deviation W(σ), this X is (for example) approximately 4% or less. Furthermore, in the slit yarn of the present invention, the abovementioned folded parts are ordinarily shape-set. X(%)=W(σ)/W(avg)×100  (1)
